Re: variable pitch propellers

<HTML>AirPlanes used one on it's 180HP conversion, they don't get the weight increase available to other fixed pitch 180 HP conversions and performance is not improved. See Penn Yan Aero website. Do you have a Lycoming or Continental?

You give up a trouble free system for one costing three times as much with no performance improvement. You may well need a new crankshaft and case, governor (plus the prop) and other expensive parts and gain 35 pounds of useless weight. If you don't go to the 180 HP you may have a difficult to sell orphan and need to find a basis for approval.</HTML>
